Title: Recording/reproducing device for optical information carrier with servo control circuit equipped and processing method of its error signal
Inventor: FUELDNER FRIEDRICH
IPC: G11B7/09
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To perform tracking correction with an inexpensive impact detector by detecting the presence/absence of disk defects or of mechanical impact and transmitting each linear and nonlinear amplified error signals to a servo controller. SOLUTION: Disk optical information from an optical scanner 1 is non- linearly amplified through a pre-amplifier 2 while the code part of the error signal is retained by a nonlinear amplifier 3. In addition, a linear amplifier 4 is installed along the nonlinear amplifier 3, with a signal outputted to an interruptible switch 5. Meantime, a defect detector 7 detects the presence of defects on a disk from a signal from the pre-amplifier 2 and, if defects such as damage or black spots exist, transmits the linear amplified error signal to a servo controller 6 through the interruptible switch 5. On the other hand, in a normal operation without defects on the disk or in the case where a recording/reproducing device receives a mechanical impact, the defect detector 7 transmits a nonlinearly amplified error signal to the servo controller 6.  Thus, a driver 8 is capable of controlling an actuator.

IPC: H03K5/08
Filed: 1987-11-10
Abstract: PURPOSE:To preclude mistriggering by making hysteresis substantially constant under the control of a microprocessor through the tracking of a trigger amplifier gain controller and a vertical axis amplifier gain controller. CONSTITUTION:A user inputs vertical gain control through a keyboard 200. The microprocessor 205 sends a specific signal to the vertical axis gain controller 125 through a digital/analog converter DAC 210 and to a trigger gain controller 125 through a DAC 220.

Consequently, the effective hysteresis that a trigger comparator may has can be made constant to preclude mistriggering. Further, the resolution of a necessary trigger level is made invariably constant and through rate performance required to a trigger circuit is reduced as well.

Filed: 1985-12-20
Abstract: PURPOSE:To record an image which always maintains a designated gradation correctly and uniformly by detecting the temperature of a thermal head and controlling the amount of energy to be injected into a thermal head using said temperature as a parameter. CONSTITUTION:The temperature of a thermal head 6 is converted to voltage fluctuations by a temperature sensor 8, and these fluctuations are input to a temperature control circuit 10 through an A/D converter 9 as temperature data. In the meantime, several kinds of energization time width data per color are stored in an energization time width data memory 5. The temperature control circuit 10 always detects the temperature of the thermal head 6 during printing and selects any appropriate energization time width data corresponding to the temperature of the thermal head 6 from the content of the energization time width data memory. Thus the change of an ambient temperature or the change of actual image density due to the accumulated heat of the head or the change of color can be prevented.
